IT'S NOT FOR ALL DOGS Purina ONE True Instinct formula is specifically formulated for ADULT dogs.
Please allow 7 - 10 days to ease the transition form your dog's current food. Each day, simply feed a little less of the previous food and a little more Purina ONE until you're feeding Purina ONE exclusively. This gradual transition will help avoid dietary upsets.

Tailored Nutrition for Every Pet
Purina One Smartblend formulas are made with high-quality ingredients, delivering the taste dogs love and the nutrients they need. These dry and wet food recipes are inspired by nature and advanced by science to give your dog a complete and balanced meal with real meat, fish or poultry as the number one ingredient. With selections for dogs of every age and breed, plus formulas that target weight and sensitivities, you'll find the perfect Purina One for your pup.


Premium Smartblend for Adult Dogs
Adult dogs will enjoy Premium Smartblend real lamb or chicken formulas with the exciting texture combination of tender, meaty morsels alongside a classic crunchy kibble. Nutrient-dense True Instinct has even more soft morsels of meat with two animal proteins. If you want to go grain-free and all-crunch, Smartblend True Instinct with beef and sweet potato could be your pup's new favorite.
Puppy and Senior Health
Purina provides the ideal diet to keep your pet healthy throughout his life with life-stage specific dry foods. Smartblend Healthy Puppy gives growing puppies high levels of essential nutrients, including protein and DHA for vision and brain development. Once your pooch reaches age 7, the Vibrant Maturity 7+ Senior formula helps nourish his mind with enhanced botanical oils that provide energy for the brain.


For Dogs Big and Small
Small breeds can benefit from Small Bites Beef and Rice, a kibble that's easy to eat with bite-size pieces. And for the big dogs, Smartblend Large Breed formulas help maintain an ideal body condition that minimizes the stress placed on bones and joints. Puppies get just the right amount of protein, vitamins, minerals and glucosamine to help them grow at the right pace, and Large Breed Adult continues the delicate balancing act of key nutrients for strong bones and muscles.
Targeted Nutrition
By researching different ingredient combinations, Purina One created Targeted Nutrition formulas that are optimized for your pet's lifestyle. With 25% less fat and 15% fewer calories than the Lamb and Rice Adult formula, Smartblend Healthy Weight promotes a naturally healthy weight. Sensitive Systems is a diet designed to nurture sensitive skin and stomachs with rice and oatmeal that are easy to digest, plus omega-6 and vitamin E for a radiant coat.


Delicious Wet Food Entrées
Serve it as a complete meal or topper—either way, Purina One wet food satisfies cravings with tasty real chicken, duck, turkey, venison, lamb and beef entrées. Choose from Classic Ground or Tender Cuts in Gravy—both have twice the recommended antioxidant levels with zinc, selenium, and vitamins A and E. For a nutrient-dense meal with two different protein sources, True Instinct's a great choice, and it comes in grain-free formulas for sensitive pets.

OK but wouldn't use it
By Zoey on Jan 3, 2021
I might be wrong, but to me grain free implies gluten free. I sent a question to Chewy, "does grain free have gluten it it?" They replied, "It has gluten it it." I asked another question, "if it has gluten in it, is it added?" Their reply, "It has gluten in it." Gluten comes in many forms but I really don't want a product that has it added for a filler. I also couldn't read the ingredients list from the picture on the website.

NO FIGHTING FOR THE DOGS TO EAT.
By HEIDI524 on Jan 12, 2021
WE HAVE FIVE DOGS AND THIS IS THE FIRST TIME WE DO NOT HAVE TO TRICK THEM INTO EATING THEIR FOOD. AS SOON AS THE FOOD HITS THE BOWLS THEY ALL EAT UNTIL NO MORSELS ARE LEFT. WE ARE HUGE PURINA DOG FOOD FANS, BUT THIS ONE HAS HIT #1 IN OUR HOUSEHOLD.

My dog loves it
By Blinggal on Jan 9, 2021
My dog is very picky and she really loves this formula. My grocery store doesn’t carry the larger bag so I’m glad I can get it from Chewy. I’m on auto delivery so it comes right to my door and I save money. Win win!

Good Food is Essential
By Kenn on Dec 11, 2020
This seems to be a very good item. My multiple dogs ate away, and you can visibly see shiny coats, less waste, healthier coloration of the waste as well. I have been using Purina One for years and they do a good job.

My dog loves it but...
By Ehhh on Nov 11, 2020
My dog loves it, but ever since hes been on it, he salivates very very excessively, like pools all over my house for hours! Unsure if its related but we're changing his food to see if its causing the issue. He loves the food but I dont want to give it to him if hes being harmed by it.

My dogs were not fans of this
By Andi on Sep 3, 2020
My dogs have been very itchy this summer and although they are currently on a grain free dog food, my vet suggested I try another one thinking there may be something in their food that they are allergic to. I switched to this and they are not fans of it at all (and their itching hasn't gotten any better). Thankfully I had more of their old food still so we are back to that but my boys must be divas because they are not fans of this unfortunately (but they LOVE Chewy.com!).

Good Smelling Dog food
By TheGrowlPals on Jan 14, 2021
In fact they carry mouthfuls to their favorite place to eat it. Then go back for more.

Our dog’s favorite
By Lulu on Sep 3, 2020
Our dog loves this dog food. We adopted her from the animal shelter at about 5 years of age, so we don’t know what she ate before. But, she clearly has gotten stronger and healthier eating this Purina food. I initially picked this for her because our cat, a stray who just showed up one day, has eaten nothing but Purina cat chow as long as we’ve had him. He is so alert, so energetic, so healthy with the silkiest fur from eating this food.

Healthy and dogs like it!
By Nana on Sep 6, 2020
I even moisten this food for my 3 pound chihuahua who has a very sensitive tummy. She has been on prescription food for 10 years and her tummy is actually doing better on this food!!!! I am even weaning her off of some of her tummy meds and her bowels are doing so well! I am delighted!!!! I got this food for my 1 year old dog who also loves it and had a bad tummy for months on other food. I am pleased.
